Late‐Stage Functionalization of Peptides on the Solid Phase

open access: yesAngewandte Chemie International Edition, EarlyView.
Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.

A Revised Model for Muscarine Biosynthesis Involving Lysine Trimethylation

open access: yesAngewandte Chemie, Volume 138, Issue 24, 8 June 2026.
The fatal mushroom toxin l‐(+)‐muscarine is one of the most prominent natural products. We elucidated its biosynthetic origin in the sweating mushroom Collybia rivulosa based on incorporation of stable isotope‐labeled compounds and extensive mass spectrometric analyses.

Thiol-Yne click chemistry of acetylene-enabled macrocyclization

open access: yesNature Communications, 2022
Thiol–yne coupling is a reliable method to link two molecular units, but has not been extensively explored for the construction of macrocycles. Here, the authors use gaseous acetylene, the simplest alkyne unit, to synthesize a variety of macrocycles ...

Recent Advances in Macrocyclic and Macrocyclic-Based Anion Receptors

open access: yesSupramolecular Chemistry, 2008
The interest in anion coordination chemistry has growth enormously in the last few years. Macrocyclic and macrocyclic-based architectures are at the forefront of the development of new anion receptors. This minireview is intended to illustrate some of the goals achieved recently in this field highlighting examples appeared in the literature over the ...

Macrocyclic ligands on polymers [PDF]

open access: yesPure and Applied Chemistry, 1979
Abstract The ion binding properties of linear polymers carrying crown ether ligands as pendent groups are reviewed. The polymers often exhibit selective cation binding different from that of their monomeric crown analogues. One of the polymers, poly(vinylbenzo-18-crown-6), behaves in water as a neutral polysoap and strongly interacts with organic ...
